My dd is 2.5 and very loved/cherished
she was an easy baby but my word she is hard work now! i have a ds 5 who didn't sleep as a baby and cried a lot but he was a much quieter and contained as a toddler
she is loud, has terrible table manners, no power of reason and throws herself on the floor in fits of rage frequently about seemingly unavoidable matters
okay i am being a bit tongue and cheek, i know that is pretty standard toddler stuff 
but i am losing patience, shouting more and even being rough with her at times 
any tips welcome
